    Cultural stewardship in urban spaces: Reviving Indigenous knowledge for the restoration of nature
    (John Wiley & Sons Ltd on behalf of British Ecological Society, 2024-08-01) Walker E; Jowett T; Whaanga H; Wehi PM; Ens E
    Relationships to nature are important for the health and well-being of peoples globally and should be actively protected. Indigenous Māori people in Aotearoa New Zealand recognize this important relationship to nature through narratives of lineage and express this through concepts such as kaitiakitanga; a cultural place-based practice of stewardship that intertwines relationships of responsibility between people, nature and culture. However, many Māori now live outside of tribal areas in urban settings, putting relationships with nature into question. We asked how urban Māori people practice kaitiakitanga, and what factors might predict flourishing relationships with nature. We surveyed 214 urban Māori who shared their perceptions of kaitiakitanga, cultural practices and restoration activities. The data were analysed by identifying qualitative themes and using linear mixed effect models. Māori who were exposed to kaitiakitanga as children were more likely to attend marae and family restoration activities, and less likely to attend events led by local councils. Pressingly, young people in urban areas were more at risk of losing cultural knowledge and opportunities to practice cultural practices in urban areas. Age, distance from tribal area and early exposure all affected decision-making and expression of kaitiakitanga in urban areas. Knowledge associated with kaitiakitanga can create inclusive and effective urban restoration activities. We suggest that partnership between Māori groups including local marae, and local councils, may provide accessible, best practice urban restoration models that attract local Māori and act to support cultural knowledge, in turn encouraging diverse pathways to nature restoration to develop in urban areas. Likewise, such partnerships will ensure that Māori in cities are supported to express and maintain cultural knowledge and practice into the future.

    Tolerance for nutrient imbalance in an intermittently feeding herbivorous cricket, the Wellington tree weta.
    (PUBLIC LIBRARY SCIENCE, 2013) Wehi PM; Raubenheimer D; Morgan-Richards M
    Organisms that regulate nutrient intake have an advantage over those that do not, given that the nutrient composition of any one resource rarely matches optimal nutrient requirements. We used nutritional geometry to model protein and carbohydrate intake and identify an intake target for a sexually dimorphic species, the Wellington tree weta (Hemideina crassidens). Despite pronounced sexual dimorphism in this large generalist herbivorous insect, intake targets did not differ by sex. In a series of laboratory experiments, we then investigated whether tree weta demonstrate compensatory responses for enforced periods of imbalanced nutrient intake. Weta pre-fed high or low carbohydrate: protein diets showed large variation in compensatory nutrient intake over short (<48 h) time periods when provided with a choice. Individuals did not strongly defend nutrient targets, although there was some evidence for weak regulation. Many weta tended to select high and low protein foods in a ratio similar to their previously identified nutrient optimum. These results suggest that weta have a wide tolerance to nutritional imbalance, and that the time scale of weta nutrient balancing could lie outside of the short time span tested here. A wide tolerance to imbalance is consistent with the intermittent feeding displayed in the wild by weta and may be important in understanding weta foraging patterns in New Zealand forests.
